What food should people with poor kidneys eat less?

Kidney can help the human body to filter the waste in blood, maintain the balance of fluid in the body, and also play an important role in regulating blood pressure. Generally speaking, people with impaired renal function should maintain healthy blood pressure and control blood sugar. This also requires patients to pay more attention to diet, especially to avoid foods high in salt, sugar and trans fat.

What foods should be avoided if there is a kidney problem? 1, processed food and fast food

Processed food and fast food usually contain a lot of salt, sugar and unhealthy fat. It is right for people with kidney problems to avoid eating these foods. This includes snacks, such as French fries, biscuits, prepackaged frozen food, canned soup and other convenience foods. Even seemingly healthy foods, such as canned vegetables and fruits, may contain a lot of salt or sugar. If there are really no fresh agricultural products to choose from, choose low-sodium canned food or frozen vegetables and fruits.

2. Excessive protein

For patients with kidney problems, doctors usually remind them to limit their daily intake of protein, because excessive intake of protein may worsen kidney problems. Therefore, beans, eggs, meat and other plant or animal proteins should be eaten less.

3. Dairy products

Dairy products are similar to protein of other animals. Studies have shown that the intake of dairy products increases the excretion of calcium in urine, which is related to the increased risk of kidney calculi. Reducing dairy products can help people with renal failure and kidney disease, because it can make kidney filtration easier.

4.caffeine

Caffeine in coffee, tea, soda and food can also put pressure on the kidneys. Because caffeine is a stimulant, it can stimulate blood flow and increase blood pressure and kidney pressure. A study shows that long-term intake of caffeine will aggravate chronic renal failure in obese and diabetic patients. By increasing the excretion of calcium in urine, caffeine intake is also related to the formation of kidney calculi.

5. Foods rich in potassium and phosphorus

According to the types and severity of kidney diseases, it is suggested to eat foods with high potassium and phosphorus content reasonably, because these minerals will accumulate in the blood when renal function is abnormal. Therefore, it is best to avoid using salt substitutes with high potassium content and limit foods rich in potassium, such as milk, yogurt, bananas and other fruits and vegetables, nuts and beans. Foods with high phosphorus content include most soft drinks, dairy products, nuts, liver and beans.

When the renal function is abnormal, the blood potassium level may rise to an abnormal level, which is often affected by diet. At this time, symptoms such as vomiting, fatigue, numbness and weakness are prone to occur. Therefore, if the body has these symptoms, it is necessary to go to a regular hospital for examination and treatment in time.
